This was tested in people. That is the most reliable kind of research we share.
This surgery and implant are already used at some hospitals, but this was a small look back at past patients, not a proper trial.
The short version
After surgery for a tumor in the bone around the eye, custom-made implants helped most patients' eyes sit and work better.
What was studied. Doctors at one hospital looked back at 13 adults who had a spheno-orbital meningioma, a tumor that grows in the bone around the eye. Each person had the tumor removed and the bone rebuilt with a custom implant made of PEEK, a strong plastic, planned in advance on a 3D computer model.
What they found. Before surgery, 10 patients had a bulging eye or double vision. After surgery, nine patients were better. On average, the difference in how far forward one eye sat compared to the other went from 4.3 mm before surgery to 2.1 mm after. Patients were followed for about 21 months on average.
What this means, and what it doesn't
What it could mean: For people facing this kind of surgery, a custom implant may help the eye sit closer to normal and may ease double vision. The doctors here felt it was safe in their hands. If you are having this surgery, it is fair to ask your surgeon whether custom planning and a custom implant are options for you.
What it doesn't mean: This does not mean a cure. The tumor surgery itself is what removes the tumor. The implant is about rebuilding bone and eye position, not about killing tumor cells. This was a small look back at 13 patients at one hospital. There was no comparison group, so we cannot say this way is better than standard rebuilding. The authors also suggest a new way to sort these cases, but that idea has not been tested yet.
